As the electronic device 20 continues to move downward, the electronic device 20 pushes the hook 1134 along the inclined surface 1134b to move the first moving member 113 in the direction D1. The first moving member 113 moves to the release position.

In this embodiment, the docking base 110 further includes a first elastic member 117 disposed between the column 119 of the housing 111 and the main body 1132 of the first moving member 113. One end of the first elastic member 117 is disposed on the cylinder 119 of the housing 111, and the other end of the first elastic member 117 is disposed on the main body 1132 of the first moving member 113, so as to generate a The elastic force allows the first moving member 113 to return to the buckle position. When the electronic device 20 pushes the hook 1134 along the inclined surface 1134b to move the first moving member 113 to the release position along the direction D1, the first elastic member 117 is elongated. Therefore, the elastic potential energy of the first elastic member 117 when the hook 1134 is in the release position is greater than the elastic potential energy of the hook 1134 when the hook 1134 is in the buckle position.

Since the first elastic member 117 accumulates greater elastic potential when the hook 1134 is in the release position, when the hook 1134 passes through the hook groove 22 of the electronic device 20 and is no longer pushed by the electronic device 20, the first elastic member 117 is The accumulated elastic potential energy is released, and the hook 1134 is brought back to the buckle position.

The first moving member 113 moves to the release position. At this time, the hook 1134 will not be engaged with the buckle slot 22 of the electronic device 20, and the electronic device 20 is suitable for being pulled up and separated from the expansion device 100. In addition, when the user releases the toggle 112 and the hook 1134 receives no external force, the first elastic member 117 resets the hook 1134 to the buckling position.

FIG. 5 is a partial schematic diagram of the expansion device of FIG. 1 in a third position. 2 and 5, in this embodiment, the anti-theft lock assembly 30 is, for example, a Kensington Lock, which is a commonly used anti-theft lock assembly for anti-theft of electronic products in shopping malls. That is to say, the present invention can achieve the purpose of locking the electronic device 20 and the expansion device 100 at the same time by using the existing common anti-theft lock assembly.

The anti-theft lock assembly 30 has a cable 34 that can be connected to or wound around objects that are not easy to move, so as to prevent the object locked by the anti-theft lock assembly 30 from being stolen. The locking hole 1141 of the fixing member 114 is elongated, and one end of the anti-theft lock assembly 30 is provided with a elongated locking member 32, and the locking member 32 is suitable for aligning with the locking hole 1141 to pass through the fixing member 114.

The anti-theft lock assembly 30 is detachably disposed on a side of the fixing part 114 opposite to the second moving part 115. When the electronic device 20 is locked to the expansion device 100 and the hook 1134 is in the buckle position, when the user wants to restrict the electronic device 20 to the expansion device 100, the locking member 32 is aligned with the shape of the locking hole 1141, and the lock The fastener 32 passes through the locking hole 1141 of the fixing member 114 and pushes against the second moving part 115 in the opposite direction D2, and the second moving part 115 moves in the opposite direction D2 and abuts against the main body 1132 to stop the first moving part 113 from being buckled. Position, as shown in the third position P3 in Figure 5.

At this time, the user uses the key to rotate the lock member 32 by 90 degrees. After the lock member 32 is rotated, the lock member 32 is staggered from the lock hole 1141. Therefore, the lock member 32 cannot be withdrawn from the lock hole 1141, so that the anti-theft lock assembly 30 is fixed to the fixing member. 114 on. In this case, the locking member 32 abuts against the second moving member 115, and the second moving member 115 abuts against the main body 1132 to restrict the movement of the main body 1132 in the direction D1. Therefore, the main body 1132 cannot drive the first moving member 113 in the direction. D1 slides, but stops the first moving part 113 at the buckling position. At this time, the electronic device 20 cannot be separated from the expansion device 100, and the anti-theft lock assembly 30 must lock the electronic device 20 and the expansion device 100 at the same time.

In addition, the docking base 110 further includes a second elastic member 118 disposed between the housing 111 and the second moving member 115. One end of the second elastic member 118 is disposed on the housing 111, and the other end of the second elastic member 118 is disposed on the second moving member 115. The second elastic element 118 provides an elastic potential when the second moving element 115 is pushed against the first moving element 113 for the second moving element 115 to reset. That is, the elastic potential energy of the second elastic element 118 when the second moving element 115 is pushed to the main body 1132 is greater than the elastic potential energy of the second moving element 115 is not yet pushed to the main body 1132.

When it is desired to unlock the electronic device 20 and the expansion device 100 by the anti-theft lock assembly 30, the lock member 32 is rotated 90 degrees with a key, so that the lock member 32 is aligned with the lock hole 1141 and can be withdrawn from the fixing member 114. The locking member 32 no longer abuts against the second moving member 115.

Since the elastic potential energy of the second elastic element 118 when the second moving element 115 is pushed to the main body 1132 is greater than the elastic potential energy of the second moving element 115 when the second moving element 115 has not been pushed to the main body 1132, when the second moving element 115 is no longer When pushed by the locking member 32, the second elastic member 118 resets the second moving member 115, that is, the second elastic member 118 pulls the second moving member 115 back to the first position P1 as shown in FIG. 3 along the direction D1. The location of the second moving part 115 in the middle. At this time, the second moving member 115 no longer abuts against the toggle 112, and the user can move the toggle 112 in the direction D1, thereby driving the first moving member 113 to slide in the direction D1, and release the hook 1134 and the hook. With the engagement between the slots 22, the expansion device 100 can be pulled up and detached from the electronic device 20.

To sum up, in the expansion device of the present invention, when the anti-theft lock assembly is not locked, the hook is located at the buckle position, there is a gap between the second moving part and the main body, and the main body drives the hook to be suitable for moving along the direction. The second moving part moves to move the first moving part to the release position. At this time, the electronic device can be separated from the expansion device. When the anti-theft lock assembly passes through the lock hole of the fixing piece, it pushes against the second moving piece, so that the second moving piece abuts against the main body to stop the first moving piece at the buckling position. In this way, the anti-theft lock assembly can restrict the separation of the expansion device and the electronic device, thereby realizing simultaneous anti-theft of the expansion device and the electronic device when only one anti-theft lock assembly is used.
